Mercedes-Benz E 63 AMG Posaidon RS850+


The Mercedes-AMG E63 has been the subject of numerous tuning jobs, as has been the case since the four-door saloon was unveiled in 2013. It may not be as known as Brabus or Wheelsandmore, but Poseidon sure knows how to get one’s attention, thanks in large part to an engine upgrade program that helps raise the car’s output to a silly 1,020 horsepower and 1,032 pound-feet of torque.


The result is an incredible 1,020 horsepower and 1,032 pound-feet of torque, enough to propel the AMG E 63 from a standstill position to 62 mph in just 2.8 seconds to go with an electronically limited top speed of 217 mph. Posaidon did post a theoretical top speed of 229 mph, but opted for the safer 217 mph on account of taking care of the tires.

Poseidon’s program, called the RS850+, also has upgrades on the exterior and interior, in addition to modifications to the suspension, and a new set of wheels. There are plenty of details to go by here, but the real interesting part about this kit is the way each section was modified to work in concert with the other sections to create a full-blown tuning experience that might actually be a little better than what a world class tuner like Brabus has to offer.


That’s of course subject to interpretation but nobody can deny that Posaidon’s work on the AMG E63 is the kind of tuning wizardry that turns a high-performance, four-door sedan into a world-beating machine on four wheels.

There’s no word yet on pricing for the RS850+ tuning program. Given the exhaustive work put into this kit by Posaidon, I won’t be surprised if the whole program ends up costing more than US$ 200,000, donor car included.
